Bio-Adhesives: Effect of Diamine’s Chain Length
Get PDFThe production of ecologically friendly items from renewable feedstock is essential to lessening the demand for non-renewable resources like petroleum-based products. High-performance polymers are formed in large part by plant oils. Still, adjustments are necessary for improved performance. Making polymers from renewable and environmentally friendly materials such as epoxidized plant oils (EPOs) is one way to attain sustainable development in the materials industry. To improve the qualities of EPO-based polymers, crosslinking agents comprising large concentrations of functional groups can be employed in polymers. In this work, highly branching and flexible polyamine was crosslinked with epoxidized soybean oil (ESO) using ring-opening and amidation polymerizations, yielding a unique resin with novel characteristics and a wide range of potential applications. ESO was used in this work to create a matching polymer through a deamination reaction with aliphatic amines like ethylene, butane, and pentane diamine at 195 °C while ammonium chloride was present as a catalyst. Solvent-free procedures that don\u27t need purification or premodifications are among their benefits. This was an easy-to-use and environmentally friendly method. With a steel metal bonding strength of 1996 kPa, MPD-ESO remained the strongest structural adhesive among the synthetic resins even after curing. Steel is always superior, no matter what the temperature. According to strength measurements using MED-ESO resin, steel has a lap shear strength of roughly 300 kPa at 100°C, which is significantly higher than that of copper and aluminium. This figure rises by an additional 750 kPa at 180°C. At 180 °C, the shear strength of MPD-ESO resin is 1996 kPa, whereas that of MBD-ESO resin is only 1220 kPa. The goal of this investigation on increasing chain length was to ascertain how the resin\u27s mechanical and thermal properties changed. TGA verifies that as chain length increases, T5%, T10%, and Tmax temperatures rise as well. As we proceed from ethylene diamines to pentane diamines, steel bonding strength likewise rises
Influence of Smart Traveler Companion Android Application on Tourist preferences in India
Get PDFAlthough most people like to travel, it might take hours, weeks, or even months to organize a trip in order to discover the right place to visit at the right time. An itinerary would be chosen, preferences would be chosen, the amount of time to spend at each location would be estimated, routes would be determined by connecting with maps and determining the most convenient routes, etc., all within a particular time range. In order to get the most satisfied out of the travels, tourists and travelers today waste a lot of time organizing and selecting their destinations. This Android application enables tourists to create customized or general travel itineraries. Based on his or her tastes, it offers a trip schedule that includes restaurants, tourism attractions, and lodging. It makes recommendations for locations and neighborhoods based on what the tourists like. Along with popular tourist destinations, tourists may discover neighboring options for lodging, dining options, etc. By offering tourists the optimized travel itinerary based on their interests and preferences, the Smart Traveler Companion application saves the time and facilitates a simple and satisfied travel experience. This Android application follows the phenomenological research method. Participants can be travel agents and end users. The importance of the study is to see if the application allows the user to be more efficient in the travel planning. The Application also provides destination suggestions and application is user-centric. The research is conducted with the aim of determining desires of the tourists in India and the application is only used by Android users
